IMPROVEMENT IN SOLDERlNG-MACHINES.

Specification forming part of Letters Patent No. 132,286, dated October15, 1872.

To all whom it may concern:

Be it known that I, J oHNA H1LDRETH,Jr., of Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented certainImprovements in Soldering-Machines, of which the following is aspecification:

Nature and Objects of the Invention.

My invention relates to improvements in the devices for operatingsoldering-irons, and though it may be employed elsewhere is intendedmore particularly to be applied/to` soldering fruit and other cans; andconsists, first, in the employment of a tube sharpened at its end toperforate the top of the can and support the soldering-iron and itsaccessories, said tube -being hollow and perforated or slotted to allowthe escape of air from the can in the soldering process, andscrew-threaded near its lower end for the reception of a crow-foot tobear upon the cap and prevent its springing. My invention furtherconsists in the employment of a hollow cylinder, in which the tube whichsupports the soldering iron accurately fits, and in which thesupportingtube may be vertically adjusted by a setscrew for solderingirons of varying lengths. My invention further consists of a plate orarm provided with a slot embracing the supporting-tube, said arm havingperforations for the reception of the soldering-iron, and slidingvertically on a tube, enabling thereby a vertical and horizontal orradial adjustment, and a rotary motion of the soldering-iron around thesupporting-tube as an axis. f

Description ofthe Drawing.

Figure 1 is a vertical longitudinal section of a soldering-machineembodying my invention. Fig. 2 is a bottom view of the slotted arm andAcap which holds the soldering-iron. Fig. 3 is General Dscription.

c is the supporting-tube of the soldering apparatus, the lower end ofwhich rests at the center of the top face of the can to be soldered. Thesupporting-tube a is made hollow, and is sharpened at its lower end toperforate the can at the center of its top, it being found neccessarythat an air-hole should be made in the can in the soldering process. b bare perforations in the hollow tube c for the escape of air from thecan. A screw-thread may also be cut on the supporting-tube c, to which acrowfoot a may be screwed or otherwise attached for soldering inlarge-sized cans to prevent springing. c is a hollow cylinder of greaterdiameter than the tube a, the latter fitting aocurately in the former,and capable of being slid up or down in it and held in any desiredposition by the set-screw d passing through the collar e on the lowerend-of the hollow cylinder c. By this construction it will be seen thatthe supporting-tube may readily be adjusted vertically. The upper end ofthe hollow cylinder c terminates in a handle, f, by means of which theoperator can hold the supporting-tube and its accessories in properposition, u and make the perforation before described in the top ofthecan. gis an arm provided with a slot, h, through which the tube epasses, and having perforations i i in its Aouter end for the receptionof the handle of the soldering-iron, which can, by its insertion intoone or other of the holes i i, be adjusted horizontally at differentdistances from the supporting-tube c, and also be adjusted vertically. kis a collar on the tube l surrounding the hollow cylinder o and tube m,the latter being provided with an annulus, n, turning in the collar k. oo are projections or pins on the lower face of the collar k and on eachside of the slotted arm g. p is a T-shaped block having a lug fitting inthe slot of the arm g, through which a set-screw passes, thus securelyattaching the collar 7c to the slotted arm, and permitting a horizontaladjustment of the soldering-iron by moving radially the arm g,v

and then fastening the T-block p. On the upper end of the tube Z is thehorizontal bevelgear wheel g, which engages with the bevelgear roperated by thel crank s, the axis of which is secured t the square boxt, which is fastened to the tube m by a set-screw, which passes throughsaid tube and operates in a vertical groove, n, in the upper end of thehollow cylinder c. e is a handle attached to the box t, by means ofwhich it may be raised or lowered. By this constructionv a rotary motionClaims.

I claim as new and of my invention- 1. The combination of the perforatedand hollowr supporting-tube a., adjustable tube c, crow-foot af, slottedand perforated arm g, atcaching-collar 7c, and T-shaped block p, allconstructed and arranged to operate as set forth.

2. The slotted arm g, constructed as set forth, l

in combination with the collar 7c, T-shaped block p, tube l, andbevel-Wheels q 7', for giving rotary motion to the soldering-iron, asde'- scribed.

3. The box t, provided With a set-screw and tube m, in combination withthe tube c provided With a groove, in which said set-screw operates, asand for the purpose set forth.

4. The collar k, provided with pins o o, slotted arm g, T-shaped blockp, and handle f, (see Fig. 4,) by means of which the solderingiron maybe rotated and vertically adjusted by the handle, in the manner and forthe purpose set forth.
